Frequently Asked Questions

Q: Can the ADL series be used with DIY balcony solar kits?

Yes, the single-phase models are perfectly suited for balcony energy storage and DIY solar kits, providing accurate monitoring of energy fed into the home grid.

Q: What is the advantage of RS485 communication in power meters?

RS485 allows for stable, long-distance data transmission, enabling the meter to communicate directly with inverters and smart home management systems for automation.

Q: How do I choose between the 80A, 120A, 200A, and 300A options?

The choice depends on your maximum peak load. For residential homes, 80A-120A is usually sufficient, while commercial installations often require 200A or 300A models.

Q: Does the meter support three-phase power systems?

Yes, the ADL400N-CT model is specifically designed for three-phase grids, supporting nominal voltages up to 400V.

Q: What is the role of the CT sensor in this power meter?

The Current Transformer (CT) sensor allows the meter to measure current by detecting the magnetic field around the wire, eliminating the need to break the circuit for installation.

Q: Is the ±0.5% accuracy sufficient for commercial energy auditing?

Absolutely. A ±0.5% accuracy rating meets professional industrial standards, ensuring that energy production and consumption data are highly reliable for financial auditing.
